The class war between the tenantry and their landlords, therefore, which is now undoubtedly waging in Ireland cannot be attributed to the historical grievances of the Irish people. The tradition and the memory of these historical grievances may indeed be used by designing or hysterical traders in agitation to inflame the present war. But the war itself is not the old war, nor can it be explained by recurring to the causes of the old war. It has the characteristics no longer of a defensive war, nor yet of a war of revenge absolutely, but of an aggressive war, and of a war of conquest. In his able work on "The Land Tenure and the Land Classes of Ireland," Dr. Sigerson, writing in 1871, looked forward to the peaceful co-existence in Ireland of two systems of land-holding, "whereby the country might enjoy the advantage of what is good in the 'landlord,' or single middleman system, and in the peasant proprietary or direct system." What we now see in Ireland, after nearly twenty years of legislation, steadily tending to the triumph of equal rights, is an agitation threatening not only the "co-existence" of these two systems, but the very existence of each of these systems. To get at the origin and the meaning of this agitation we must be content, I believe, to go no further back than ten years, and to look for them, not in Ireland, but in America, not to Mr. Parnell and Mr. Gladstone primarily, but to Mr. Davitt and Mr. Henry George. III. In a very remarkable letter written to Earl Grey in 1868, after the Clerkenwell explosions had brought the disestablishment of the Irish Protestant Church into Mr. Gladstone's scheme of "practical politics," the Archbishop of Westminster, not then a Cardinal, called the attention of Englishmen to the fact, not yet I fear adequately apprehended by them, that "the assimilating power of America upon the Irish people, if seven days slower than that of England in reaching Ireland, is sevenfold more penetrating and powerful upon the whole population." By this the Archbishop meant, what was unquestionably true, that even in 1868, only twenty years after the great Irish exodus to America began, the social and political ideas of America were exerting a seven-fold stronger influence upon the character and the tendencies of the Irish people than the social and political ideas of England. Thanks to the development of the cables and the telegraph since 1868, and to the enormous progress of America since that time in wealth and population, this "assimilating power" reaches Ireland much more rapidly, and exerts upon the Irish people a very much more drastic influence than in 1868. This establishes, of course, a return current westward, which is as necessary to he watched, and is as much neglected by American as the original eastward current is by British public men.
